GRAIN- DRILL.

SPECIFICATIQN .forming part of Letters Patent No. 337,543, dated March 9, 1886. Application filed March 1K0, 1885. Serial No. 160,697. (No model T0 all whom, t may concern..-

Be it known that I, MILEDEN WoNsER, of Kingston, in the county of Labette and State of Kansas, have invented a new and useful Improvenient in GrainDrills, of which the following is a full, clear, and exact description.

Reference is to be had to theaccoinpanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts iu all the figures.

Figure l is a plan view, partly in section, of a part of a grain-drill, illustrating niy invention. Fig. 2 is a rear elevation of the saine, part heilig broken away. Fig. 3 is asectional end elevation lof the saine, part being broken away. Fig. 4 is a transverse section. of the shaft and cutters, showing the manner of constructing the cutters; and Fig. 5 is a detail section on line a: Fig. 4t.

The object ofv this invention is to provide grain-drills constructed in such a manner that they can be readily adjusted to deposit the grain at any desired depth in the ground.

The invention relates to a grain-drill constructed with a frame and with a series of rotary cutters mounted upon a shaft having a series of inclined sections, and pivotcd to bars sliding in grooves in stationary bars, and connected by ropes or chains and guide-pulleys with a shaft pivoted to the said franie, whereby the inclination of said cutters can be readily adjusted and the said'cutters can be readily raised and lowered. The grain is delivered at the sides of the rear parts of the rotary cutters,in the channels opened by the said cutters, by spouts supported by a bar attached to the frarneoftheinachine. Theshaft carryingtherotarycutters is made with inclined sections parallel with each other on each arm of the shaft, and inclined in inverse directions on the two arms of the shaft, as will be hereinafter fully described and then claimed.

A represents the frame of the machine. To the frame A are journaled the wheels B, upon which the machine is carried.

To the inner sides of the side bars of the frame A are attached vertical bars C, in the inner sides of which are l'orined T-grooves to receive the correspondingly-shaped sliding bars D.

To the lower ends ofthe sliding bars D are journaled the ends of the shaft E, which is formed ofa number of inclined sections. The axes of the sections upon each side ofthe center of the shalt E are parallel with each other and atan angle with the axis ofthe shaft, and the sections upon the opposite sides of the center of the said shaft E incline in reverse directions, as shown i Fig. l.

Upon the inclined sections of the shaft E are placed the hubs of circular cutters F, which inay be niade convex upon their inner sides and plane or slightly concave upon their outer sides. With this construction the cutters F upon each side of the center of the shaft E will he parallel with each other, and the cutters F, upon the opposite sides of the center of the shaft E, will be at an angle with each other, as shown in Figs. 1 and 2. With this construction, when the shaft E is turned in its bearings` the inclination of the cutters F with respect to the surface of the ground and the line of draft will be changed, so that the said cutters will be adjusted to open wider ornarrower channels by turning the said shaft E. p

In order to place the cutters on the shaft they may be foi-ined, as shown in Figs. 4 and 5, with a large central opening, f, and with sectional boxesfftted therein and secured to the cutters by bolts, or in other suitable manner.

In practice the cutters may be first slipped on the shaft to the proper position, and the box-sections be then applied.

To one end of the shaft E is attached a square-toothed ratchet-wheel. G, with the teeth of which engages the pawl H, pivoted to the frame A or some other suitable support, so that the shaft E can be readily adjusted and will be held securely in any position into which it inay be turned.

To a cross-bar, I, attached to the frame A, are attached the spouts J, by which the seed is conducted from the seed-box into the channels opened in the soil bythe cutters F. lThe lower ends ofthe conducting-spouts J are curved inward, so as to be nearly in contact with the lower rear parts of the cutters F, and thus introduce the seed into the channels opened by the cutters F before the said lchannels ha'e been partly filled by the falling in IOO of the soil at the sides of the said channels. The upper ends of the conducting-spouts J are l flared to adapt them to better receive seed from the seedAbox, which is not shown in the drawings, as there is nothing new in its construction or operation.

To the lower parts of the sliding` bars D are attached the ends ot' ropes or chains K, which pass over guide-pulleys L, pivot-ed in slots in the upper parts ofthe flanges or supports M, formed upon or attached to the bars C in the T-grooves ot' which the said bars D slide.

To the upper parts of the sliding,` bars D are attached the ends ot' ropes or chains N, which pass around `snide-pulleys O, pivoted in slots in the lower parts of the flanges or supports M. The other ends of the ropes or chains K N are wound iu opposite directions around and are attached to the shaft P, which is pivoted to the frame A, so that by turning the said shaft P the sliding,Y bars D will be raised 0r lowered to raise or lower the shalt E and cutters F, and thus adjust the said cutters to work at any desired depth in theground. The shaft l can be turned by a lever inserted in holes in the said shalt, as indicated in dotted lines in Fig. 3, or by other suitable means. lit-h this construction the machine will cnt its way and clear itseltl in land fouled by stubble, weeds, cornstalks, or similar rubbish.

By the use ot' this machine the grain can be put into the ground with less d raft-power than is required with ordinary drills.

Having thus fully described my iutiention, I claim as new and desire to secure by Letters Patent l. In a graindrill, the combination, with the frame ot' the machine and a series of cir cular rotary cutters, ofthe shaft lll, having inclined sections to receive the hubs ofthe said cutters, and a supportin't,r and adjusting mechanism, substantially as herein shown and described, whereby the inclination of the said cutters can be readily adjusted, as set forth.

2. In a grain-drill, a shalt having,` a plurality of bearingsections arranged at an angle to its axis, substantially as set forth.

3. In a grainvdrill, the shaft E, made substantially as herein shown and described, with inclined sections parallel with each other on 4each arm ofthe shaft and inclined in reverse directions upon the two arms of the shaft, as set forth.

4. rlhe combination of a rotarily-adjustable shaft having bearings arranged at an incline or angle to its axis of revolution, cnttersjournaled ou said inclined bearings,and verticallyadj ustahle supports for said shalt, whereby the cutters may be set at any desired incline and held at a common depth with each position or inclination, substantially as set forth.
